To all 'whorzt it may concern;

' Be it known that LMILLARD F; FIELD, of- Boston, in. the county of Suffolk and-State of -Massachusetts, have invented certain new and useful Improvements in Warp-Drawingin Machines, of whichlt-hei following is a. de-

scriptionisufliciently full, clear, and exact-to [enable those skilled in the art to which it appertains or with which it is-most nearly connected to make and use the same.

This invention has relation to machines for drawing the ends of the'warp-threads into the eyes of the harness orheddles and through the reeds of a loom preparatory to setting up or commencing thewea'ving of a piece "of cloth.' Itis the purpose of the invention toprovide improvements capable of use in the highest,

degree, whereby the arp threads and har 2o taint'y in a predetermined position, "so thatas "the needle is'reciprocated mechanically, as it,

will be, it willwith certainty also enter the desired dents of the reedfand the harness.- eyes-and catch the warp-threads and in .its return draw the latter in, Y It is also the object'of the invention to provide 1 other improvements "incidental to the foregoing and to as far as maybe organize a drawing-in machine which will perform 'its work aewell as, if not 'betteran'd more cen tainjthan,.handwork as ordinarily done;

novel;-means for holding -the hed'dles, and warp-threads, sethat they canhemechanice ally spacedrwith exactness; h f

when caught and pulled through the harnesseyes and dents of the reed.

The invention also consists of other improved means of importance in the organization of a machine of the character mentioned and in thecarryingont of the improvements specially designated, all as I will proceed to set forth with the requisite clearness and exactne'ss hereinafter. p Reference is to be had to the annexed draw ings, and to the letters and figures marked thereon, forming a part of'this specification,- the same letters and figures designating the sameparts or features, as the case may-be, wherever they occur.

The scrcw-rod z is provided with a gear 4, which engages and drives a pinion 5, fast on the end of the warp screw-rod a". A pini'on 6, fast on the end of the lowerheddle screw-rod b", is engaged andid'riven by the pinion 2 on the rod y, the rod 1)" being'slightlyout of parallelism'with the other rods to prevent the pinion. 6 from being en- 'gaged by the pinion 3, or, in other words, the

necessary arrangement of the said pinions' results in arranging the rod b" slightly out of parallelism with the other'rods. This, however, is an unimportantfeature and is merely" mentioned to explain the reasonswhy the said rod is represented out of parallelism.

While in the drawin the coils of wire are the entire width of the lease .or warp or of a length sufficient to extend from, side to side of a warp, it will be readily understood by those skilled in the art that this in practice is done and that the coils are simply show bro'ken 01f, lit being deemed unnecessary to the understanding of the invention to show more than is illustrated.

It will further be understood-thatthe cords 'n' will extend through the coils from end to end and-of course from side toside of the warp when the rods are withdrawn frem the coils. Furthermore, any convenient form of means may be employed for attaching-the cord at" to. the screw-rods. simple staple or loop or screw-eye may be connected with the end of the rod and the cord tied thereto, and as-the rod is drawn through the coil the cord n";will be'drawn after it, so that as fast as the rod leaves the coil it'will be replaced by 'thej'cord.

Referringfirst to the screws 3; and .z ,;respectively secured tothe ends of the heddlerods 11 and z, it maybe statedthat'thje said rods are inserted in the coils m"'in place vof the .cords n", as stated, with the cords of the heddles above the harness-eye's facing each other with respect to the-rods and screws; Then as the reds and screws are turned the For example, av
